Don't panic about the headline. The story here is that learning management systems (including, among others, Instructure's Canvas) has hooked into the Alexa API, so they can not accept (some) voice commands, and give audio responses. "This means," we are told, "that students will be able to ask Alexa key questions (e.g., What were the main points made in today’s class?), and Alexa will be able to offer a summary." For more coverage, see this report describing how Alexa is being supported by Canvas and Blackboard.
